Hacker Musings and OCD

Is my Dropbox going to sell me out?

Let us assume for a moment that I have NSFW content on my personal (paid for by me) Dropbox, which I connect to my work computer.

Am I then “storing” NSFW content on my work computer? After all Dropbox locally caches pretty much everything. If I’m using Dropbox at work for things like 1Password or syncing application config, am I obligated to ensure that no NSFW content is part of the bargain?

(Note that I am not looking at the NSFW content at work. It is just passively there. Obviously if I use Dropbox to sync NSFW content so I can look at it at work, I’m in the wrong.)
